1. Technical Field
The exemplary disclosure generally relates to an elastic member and key-press assembly using the elastic member.
2. Description of Related Art
Electronic devices typically have a keypad incorporated with a plurality of key-presses as an input terminal or a control button.
One such key-press assembly for a given electronic device typically includes a key-press and a dome shaped metallic elastic sheet, and a printed circuit board (PCB) defining a corresponding electric contact point. The key-press is mounted on the sheet over the contact point. In use, when the key-press is pressed, a bottom of the key-press deforms the sheet to touch the contact point. This configuration only allows the button to function in one way.
Therefore, there is room for improvement within the art.
Many aspects of the exemplary elastic member and key-press assembly using the same can be better understood with reference to the following drawings. These drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present elastic member and key-press assembly using the same. Moreover, in the drawings like reference numerals designate corresponding parts throughout the at least one views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
The elastic member 50 has a substantially stepped hollow dome shape, and is configured to be mounted on the PCB 20 at a position corresponding to the contact section 22 and elastically sandwiched between the key-press 70 and the PCB 20. The elastic member 50 is made of electro-conductive material, such as metal, for example. The elastic member 50 includes a pressing portion 51, a first extension 53, a second extension 55, and a connecting portion 57. The pressing portion 51 has a substantially disk shape corresponding to the key-press 70 and the first electrical contact section 222 of the PCB 20. The pressing portion 51 includes at least one contact terminals 511 (shown in

In use, referring to
Due to the special structure of the elastic member 50 of the exemplary key-press assembly 100, the key-press assembly 100 can be operated to trigger more than one function of the electronic device.
It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes can be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
